Embodiment Construction

[0021] Such as figure 1 , 2 As shown, the present invention consists of the spiral flow generator 2 and the installation pipe section. The spiral flow generator includes a fixed ring 8, an impeller 11 and a guide fluid 6. The impeller 11 is composed of three identical blades 14. The fixed ring 8 and the blades 14 are connected by welding. The overall outer contour of the blade 14 is a propeller blade type , The three blades are uniformly welded on the diversion fluid at 120° intervals, such as Figure 4 As shown, the angle α between the plane of the blade 14 and the cross section of the guide fluid 6 is 20°. The vane is provided with a deflector 12, a flow hole 13 and a serrated trailing edge 15; the deflector 12 is of a circular arc shape and is evenly distributed on the blade 14 with the deflector 6 as the center. The distance h is equal, the height of the deflector 12 is 5mm, and the number of distribution on each blade 14 is 2, such as Figure 5 As shown, the angle γ betwe...

Abstract

The invention discloses a gas-liquid two-phase helical flow generating device in a pipeline, which comprises a helical flow generator (2) and an installation pipe section, wherein the helical flow generator (2) comprises a flow guide body (6), a fixed ring (8) and three same blades (14); the whole outer outline of the blades (14) is shaped as a helical propeller blade, the inner sides of the blades are uniformly fixed on the flow guide body (6) at intervals, the outer sides of the blades are fixed on the inner side of the fixed ring (8); an included angle alpha exists between the blades (14) and the cross section of the flow guide body (6); arc flow guide plates (!2) uniformly arranged by using the flow guide body (6) as a center are arranged on the blades (14); and the installation pipe section comprises a pipe housing (3), and the helical flow generator (2) is arranged on the inlet end of the installation pipe section. The gas-liquid two-phase helical flow generating device has the advantages of good helical effect, low fluid state attenuation speed and wide applicable range.

Description

Technical field [0001] The invention belongs to a gas-liquid two-phase fluid transmission device in a pipeline, and in particular relates to a pipeline whirling device for transmitting a gas-liquid two-phase fluid. Background technique [0002] Spiral flow is a flow form with a rotating flow field. It has a wide range of industrial applications and has applications in water conservancy projects and mechanical processing. At the same time, spiral flow technology has also entered people's daily life, such as spiral flow energy-saving gas stoves. Since the spiral flow has such a wide range of applications, the conditions for its generation are very critical. Generally speaking, there are three conventional methods for generating spiral flow: tangential flow, installation of guide vanes and rotating pipes. [0003] The guide vane type spiral flow generator generates spiral flow by changing the boundary conditions of the water flow in the circular pipe. That is, a number of fixed guid...
